Recently, the company has used the WeChat public platform, so we have studied the development technology of WeChat public accounts. Generally speaking, it is relatively simple. Combined with the existing platform core technology, it is very convenient to implement.
First, let’s learn about the WeChat public platform.
“WeChat is a way of life” , this is WeChat’s self-evaluation. Do you think that if you don’t share your latest status in the circle of friends that day,
If you receive a few likes and comments, will you feel empty and lonely? It has truly changed our way of life.
" WeChat is also a way of doing business". While WeChat has become our daily essential app, it also has huge commercial potential
Perhaps it shouldn’t be called potential, because many people have already made profits. Celebrities open public accounts on WeChat to attract money, and merchants do promotion.
The service industry uses this to expand channels, and WeChat even supports it After paying, more and more self-media are emerging on the WeChat platform.
This article introduces how to quickly become a public platform developer. Since individuals can only apply for a subscription account, this article uses a subscription account as an example.
For the difference between subscription account and service account, please refer to Related instructions for WeChat public platform service account and subscription account.
In simple terms from the perspective of WeChat users:
Subscription account is mainly used for information radiation, typically such as various news media.
Service number is mainly due to self-service, typically such as China Merchants Bank.
Apply for a public platform account
- Go to the WeChat public platformfill in the registration information
- Follow the prompts to activate your email
- Upload personal photos, clear ID photos are required
- Select the type of public account. For personal accounts, you can only choose Subscription Number
- Finally you will see all the information of your account. Please upload the avatar of your account, otherwise the developer application cannot be completed
- Waiting for approval, this process will take about 2 to 3 days. When you receive the following notification, congratulations, you have successfully applied for a WeChat public account
I won’t go into details about the steps to register a WeChat public account. You can find a large number of graphic tutorials.
After the account registration is successful, you need to verify your own server. If you do not have your own server, you can use Sina SAE or Baidu BAE. This article uses the Sina SAE platform to build the server.
The registration process is brief. Use Sina SAE to create an application. You can choose an application development framework. There are popular development frameworks in the options. Select WeChat public platform phpSDK. Click to jump to the introduction page. Click to install the framework. The system will generate a For the built WeChat public platform application, in order to facilitate development, we can use svn to manage this application code. For information on svn construction, please refer to the sae code deployment manual.
It is more convenient to use Sina SAE. If we have our own server, we can clone the code to our own server. Let’s take a look at the code

Some functions of the above code require opening a service account and applying for certification, such as speech recognition, geographical information, and the function of adding menus. Applying for certification requires 300 yuan/year, and you can enjoy all the interface functions of WeChat.
Note: If you verify the server URL, you need to modify a code
<span $wechat</span> = <span new</span> MyWechat('hancong', <span TRUE</span><span );
</span><span //</span><span $wechat->run();</span>
<span $wechat</span>->validateSignature('hancong');<span //</span><span 参数为填写的token</span>
Reply to call the run method after verification. The validateSignature method is only the first verification server call and can be deleted after verification.
